Where's the best place to put object mappings in RestKit

Question

I\'m using RestKit for a project and i noticed that there is no longer a method in the class that you can control all mappings in (elementToPropertyMappings), i therefore wonder

Answer 1

I think the domain model should be the only one who should know about the mapping. Here is how I map some flickr json:

I call the mappings when you need them (Can be in AppDelegate or where ever you want)

// Setup our object mappings
RKObjectMapping *photoMapping = [Photo mapWithMapping:nil];
RKObjectMapping *photosMapping = [Photos mapWithMapping:photoMapping];

And this is one of my domain objects: It contains the classMethod doing the mapping.

#import "Photos.h"
@implementation Photos

+ (RKObjectMapping*)mapWithMapping: (RKObjectMapping*)aMapping
{
    RKObjectManager *objectManager = [RKObjectManager sharedManager];
    RKManagedObjectMapping *mapping = [RKManagedObjectMapping mappingForClass:[self class] inManagedObjectStore:objectManager.objectStore];

    [mapping mapKeyPathsToAttributes:
         @"page", @"page",
         @"pages", @"pages",
         @"perpage", @"perpage",
         @"stat", @"stat",
         @"total", @"total",
     nil];

    if (aMapping) {
        [mapping mapRelationship:@"photo" withMapping:aMapping];
    }

    return mapping;
}

@end
